To a-ZZ whom it may concern:

Be it known that I, HARTLEY FEWSON, a subject of the Queen of Great Britain and Ireiand, and a resident of the town and county of.

v ber F. 2,876', dated April 2, 1887,) of which the following is a specification.

Myinvention for improvements in the treatment of Sewer and other similar noxious gases has for' its principal object to construct an .apparatus through which any sewer or other' noxious gases passed shall be rendered harmless and incapableof assisting in the decom position of animal matter.

In carrying' my invention into practical ef- -fe'ct, the sewer or other noxious gases are drawn by a fan, punp-bellows, or other suitable apparatns from the drain or other place containing the same and are forced through apparatns of special Construction. The outer case of this apparatus consists of a box or other suitable vessel supported on glass blocks and lined throughout with glass. This box is fitted with i-nlet and outlet pipes at its opposite ends and with glass partitions arranged 'so that the gases passed through the apparatus are forced to takea z'igzag course from the inlet to the `outlet. The number of glass partitions is any suitable odd number. Each glass partition'is covered on the inlet side that is, on the side nearest the inlet of the gases-with tin-foil. A small platinun wire passes in front of each sheet of tin-foil, but at 'a short distance therefrom. A similar wire passes in front of the glass side of that plate nearest the outlet-pipe.- 'Two insulatcd electrical conductors are led into the box,and the latinum wire in front of the plate nearest to the inlet=pipes and the wires in front of each alternate plate are connected to the positivecondu'ctor. The remaining wires, including the one opposite the glass side of that plate nearest the outlet-pipe, are connected 'to the negative conductor. When the gases are to be treated, the conductors are connected, respectively, to the positive and negative pales of an electrio generator. The gases in passing through the apparatus are thus subjcted'to electrolysis and are decomposed and .form fresh combinations, oxygen being liberated from sewer or other noxious gases and ozone being forned at the last glass partition. The resultant gases delivered from the apparatus are passed into-water, the oxygen vitalized' by the presence of ozone, and the nitrogen rising' up through the water and being discharged in a harnless state.

i Iu the accompanying sheet of drawings, Figura lisa seetional plan of one form of'apparatus for the treat-ment of sewer and other oxious gases, constructed according to this invention; and Fig. 2 is a longitudinal section i of the same.

-The box A is lined with glass B, and is provided With glass partitions C, arranged as shown. The gases to be' treated enter by the pipe D and pass in a 'zigzag course, as shown by the arrows in Fig. 2,to the outlet E. Each partition C is covered on the inlet side with tin-fail., (Shown by the interrpted lines F.) Thetwo electrical conductors 1 N are led into the box, as shown, and are connected to small platinum Wires '\V, which are arranged in front of the sheets of tiu-foil and of the glass or uncovered side of the plate C, nearest the outlet, at some slight 'distance tl erefrom, the wires W being connected alternately to the conductors P N,and being supported by insulatiug-,blocks H cemented to the partitions G.

It will readily be understood that the glass maybe replaced by any suitable insulator.

I am aware of the patent to C. F.'Dunder dale, No. 100, 736, dated March 15, 1870, wherein apparatus is described for producing ozone, consisting of a box with spaces, 'plates of glass for the passage of the gas and electric current, and-therefore do not broadly claim any of these parts.

I claim as my invention and desh-e to secure by Letters Patent- In an :ppa'atus for thet'eatmeubof Sewergases, the co'binaton of the box A; lned wih glzss, theglass partitons 0,30 aranged :s to give the gas a zigzag course, the inlet ppe D, and the ouet I), 2111 combined as shown, and acted upon by an electric current, 'for the purpose set forth.

Iu testnony whereof 'I have signed my name to this specificabion in the presence of two Subscribing witnesses.
